What is Depreciation?

Depreciation is the decrease in value of an item over time due to age, wear, and obsolescence. The IRS publishes guidelines (Publication 527) that establish the "useful life" of various items in rental properties.

Key Principle

If an item has reached the end of its useful life, its value is $0. The landlord cannot charge you anything for it, even if you damaged it.

Why Depreciation Matters for Your Deposit

Many landlords try to charge tenants the full replacement cost of items like carpet, paint, or appliances. However, if these items were already old when you moved in, they have little to no remaining value.

Example: Carpet Depreciation

Scenario:

  • Carpet was 4 years old when you moved in
  • You lived there for 3 years
  • Carpet is now 7 years old
  • Carpet useful life: 5-7 years

Result:

The carpet has reached the end of its useful life. Even if you stained it, your landlord cannot charge you for replacement because the carpet was already fully depreciated.

Standard Useful Life Guidelines

The following table shows typical useful life spans based on IRS Publication 527 and industry standards:

ItemUseful LifeNotes
Carpet5-7 yearsHigher quality = longer life
Interior Paint3-5 yearsDepends on quality/traffic
Appliances10-15 yearsRefrigerator, stove, dishwasher
HVAC Systems15-20 yearsFurnace, AC units
Water Heater10-12 yearsTank-style
Window Blinds5-7 yearsMini blinds, verticals
Drapes/Curtains5-7 yearsFabric window treatments
Vinyl Flooring10-15 yearsSheet vinyl, LVP
Hardwood Floors25+ yearsWith proper maintenance
Light Fixtures10 yearsStandard fixtures
Faucets15-20 yearsKitchen and bathroom
Toilet25+ yearsPorcelain fixtures

How to Calculate Depreciated Value

Use this formula to calculate the remaining value of an item:

Remaining Value = Original Cost × (Remaining Life / Total Life)

Where Remaining Life = Total Useful Life - Age at Move-Out

Calculation Example

Paint Deduction Disputed:

  • Landlord charges: $800 for repainting
  • Paint age when you moved in: 2 years
  • Your tenancy: 3 years
  • Current paint age: 5 years
  • Paint useful life: 5 years

Calculation:

Remaining Life = 5 years - 5 years = 0 years
Remaining Value = $800 × (0 / 5) = $0

The paint was fully depreciated. You owe nothing for repainting.

How to Challenge Improper Deductions

  1. Document the age: Get move-in inspection reports, photos, or receipts showing when items were installed.
  2. Calculate depreciation: Use our free Deduction Checker to automatically calculate the depreciated value.
  3. Write a demand letter: Cite the IRS depreciation guidelines and demand a refund of the overcharged amount.
  4. File in small claims: If the landlord refuses, bring your calculations to court. Judges understand depreciation.

State-Specific Rules

Some states have specific requirements about depreciation:

  • California: Courts consistently apply depreciation. Landlords cannot charge for items past their useful life.
  • Texas: The 3x penalty for wrongful withholding applies to amounts that should have been depreciated.
  • Washington: If landlords fail to provide proper documentation, depreciation arguments are strengthened.
